APPARATUS FOR ADVERTISING PURPOSES.

SPECIFICATION forming part of Letters Patent NO. 623,641, dated April 25, 1899.

Application filed June '7, 189 8. Serial No. 682,842. (No model.)

To aZZ whom, it ntay concern.-

Be it known that 1, JOHN WVARRICK, a subject of the Queen of Great Britain and Ireland, residing at Reading, county of Berks,

England, havein vented a certain new and useful Apparatus for Advertising Purposes,of which the following is a specification.

This invention relates to improvements in the construction of apparatus for advertising purposes; and its object is to provide an arrangement which will display moving advertisements in an attractive manner.

The apparatus is adapted for use with carrier-cycles, omnibuses, tram-cars, railwaycarriages, and other vehicles. It is also applicable for display in shop windows, on hoardings, or in any other suitable position.

'I purpose displaying the advertisements in a suitably-formed case having Windows and arranged either inside or outside of any kind'of vehicles and mounted or attached in such a way that they can be seen either from the outside or inside, or both, as desired. The advertisements are arranged and displayed 2 5 upon sheets of paper or other suitable material and wound on suitable drums or rollers provided with conical flanges or small guiding-rollers. These sheets are adapted to move in a vertical, horizontal, or other re- 0 quired direction either independently or synchronously and to appear at different windows.

The apparatus I propose to employ winds up the advertisements at regular intervals,

5 so as to bring a fresh advertisement before the notice of the public at every operation. The advertisements are moved rapidly into their new position and are then held stationderstood, reference is had to the accompany-.

ing drawings, in which Figure 1 is an elevation of a cycle provided with my improved advertising-case; Fig. 2, a vertical section of the case, and Fig. 3 a sectional plan of the same. Fig. 4 is a side elevation of the mechanism I propose to employ. Fig. 5 is a plan thereof, and Fig. 6 an end'55 elevation. Fig. 7 is a detail view showing part of the winding device.

As shown in Figs. 1, 2, and 3, the case Ais provided, preferably on each side, with the windows a and a, a pair of the latter being employed placed above the former and of smaller dimensions. Fig. 1 shows the case carried on the tricycle B and supported in the usual manner between the wheels. The advertisements are displayed on the sheets O and O, the sheet 0 extending behind the window a and O behind the Windows a. C

,is wound over the rollers or drums D, these being placed horizontally, so as to wind the sheet up or down. The sheet O consists of a narrow strip extending around the top of the case and wound upon the drums D,-passing over the rollers D at the corners of the case.

The mechanism for operating the advertisements is shown more fully in Figs. 4 to 7, and consists of a driving-axle E, carrying disks F. The axle E is driven by the pulley e or by the train of toothed wheels 6, the motion being derived from the driving mechanism of the cycle or vehicle wheels or from any othersuit- 8o able mechanism when displayed in shop-windows or other position. The drumD,on which theadvertising-sheets are wound, is provided with a central spindle d, on which the bevel-wheel d is fitted. This 8 5 spindle is revolved from one of the disks F by the bevel-wheel g on the shaft G gearing into the bevel-wheel d. On the end of this shaft a toothed wheel g is mounted and is adapted to gear with the quadrant-rack f on go the inner face of each of the disks F. This rack is concentric with the disk and is shown as extending for about one-quarter of a circle; but it may be of any suitable length. The wheel g engages with one rack at a time,

the distance between the disks F being slightly greater than the diameter of the wheel. The

shaft G is supported in a frame H, which is fitted on top of the support .I, and said support may consist of a block of wood fixed to the bottom of the case A or to any other suitable base. The frame II is pivoted at 7t close to the bevel-gearing and is adapted to turn through a slight angle, the angle beiug so small that it will not interfere with the gearing. It is provided with aslot 72., and a screwj, passing through such slot,is screwed into the support J. The slot allows of the slight angular motion required, while at the same time it keeps the fratne in position for gearing purposes.

In order to change the position of the shaft, and consequently to reverse the motion, an automatic reversing device is employed, consisting, advantageously, of a toothed wheel K, placed below the axle E. This latter is furnished with a small wheel L, having a single tooth Z, adapted to engage with the teeth of the wheel K. As the axle and disks revolve this tooth causes the wheel K to turn for a short distance at each revolution, so bringing into action the cam or raised surface 1;, which extends upon the inner face of the wheel for about half its circumference. The frame II is formed with an arm or extension 7L2, which projects at an angle and bears against the face of the wheel K. On the latter revolving the cam-surface is brought around to the end of the said arm or extension and pushes it to one side, thus moving the frame and causing the small toothed wheel g to engage with the rack on the second disk. The cam-surface keeps it in this position for the next half-revolution of the toothed wheel K. To cause the frame to return when released by the cam, a spring ft? is employed and is carried by a support h. This spring bears against the frame and brings it when released toward the first disk, as shown in Fig. 5, so that it returns to this position.

To prevent the drum D turning except when operated by the gearing, it is provided with a small disk or extension (1*, in the periphery of which a notch is formed. In this notch a pawl or lever M engages, the other end extending, as shown in Fig. 5, under one of the disks. Said disk is provided with a cam-surfacef' on its circumference equal in angular length to the rackf. This cam is placed so that as the disk revolves it comesinto action and presses upon the end of the lever M. This raises the pawl or lever from the notch and releases the drum. The cam is placed so that the drum is released just before the rack f reaches the toothed wheel g. Immediately the rack has passed the wheel the cam releases the pawl or lever, and a spring at causes it to engage again in the notch, the parts beiug arranged so that the notch comes into the proper position after each operation.

On the end of the spindle (l a second bevelwheel (1" is placed, engaging with the wheel N, carried on the vertical spindle 92. This vertical spindle, as shown in Fig. 2, operates the upper part of the mechanism carrying one of the drums D, so that both advertisementsheets are worked simultaneously.

The apparatus already described moves the advertisements only in the one direction, and in order to take up the slack and to wind up the sheets in the opposite direction the arrangement shown in Fig. 7 is employed in combination with the reverse movement described. This consists simply of a spiral spring 0, carried in the case 0 and provided with the intermediate wheels 0, connected with the roller or drum D. The spring is wound up when the advertisement-sheet is unwound from the roller or drum, and the force of the spring keeps the sheet taut and also winds it up in the opposite direction when it is unwound by the mechanism before described, which then serves merely to unwind the sheet from the roller or drum to which it is connected. This clockwork mechanism may also be used to drive the axle E. The position of the case is shown in Figs. 2 and Having now described my invention, what I claim, and desire to secure by Letters Patent, is-- Y 1. In apparatus for advertising purposes, the combination with advertisement-sheets wound on rollers or drums, of two revolving disks carried adjacent to each other on a common axle, a rack on the inner face of each disk extending through a portion of a circle, a gear arranged between the disks and arranged to separately engage the racks driving connections from said gear to the rollers or drums, a toothed wheel driven from the axle-carrying disks, a cam on the toothed wheel adapted to move the gear from one disk to the other reversing the motion, substantially as described and for the purposes specified.
